1. A flow path device adjusted for observing a test solution existing in a well in a well plate, the flow path device comprising:
a plate-shaped main body having an upper surface and a lower surface as main surfaces; and
an insertion body provided in the main body, the insertion body extending along a direction perpendicular to the main surfaces of the main body, the insertion body having a pore, the insertion body being configured to be inserted into the well, wherein
the pore has a dimension capable of sucking up the test solution in the well by capillarity,
the pore extends from a tip of the insertion body to a first position between the upper surface and the lower surface of the main body, and
the main body includes:
an observation flow path which extends from a first end to a second end within a plane parallel to the main surfaces, the observation flow path having a predetermined flow path length, wherein the first end of the observation flow path communicates with a portion of the pore at the first position; and
an exhaust hole extending from the second end of the observation flow path to the upper surface of the main body in a direction orthogonal to the observation flow path, wherein the exhaust hole is connected to an opening communicating with an outside of the flow path device.
